As hereinafter more specifically pointed out,
the objects and advantages of this invention are
realized by providing an improved door construc
tion which has the side or supporting frame
members for the main door located beyond or
outside of the depending aprons of the hopper,
and providing a secondary door which occupies
the entire space between the opposed apron

control the discharge of such lading.

this invention is illustrated as embodied in a car
having a center sill I0 and side sills II, which
form the main supporting framework for the
body of the car. The car body consists of side
walls I3, en_d walls I4 and end slope sheets I5
which direct the lading of the car centrally to
the hopper openings I6 shown in Figure 4. Over
lying the center sill is the usual inverted V shed
ding plate I'I and on the outside of the two hop
pers I6 are shedding surfaces I8. At the central
portion of the car or at the' location between ad
jacent hoppers are shedding surfaces I9, which

As clearly shown in Figure 5, the secondary
door plate 49 is of such length as to fully close
the opening between the hopper aprons _30, and
the arms 43 of the main door section extend
closely adjacent the outer faces of the aprons 30.
The‘door assembly is operated to open the en
